Subject: Lightning engine temps
My problem is the opposite of what most owners are complaining about. I ha
ve a lightning with the stock firewall forward setup. Even in the summer w
ith the normal high desert temperatures my CHT's run between 235 and 265 de
grees except #2 which seldom exceeds 205 degrees. My oil temperature will
not exceed 170 degrees unless I completely block the air vent for the finne
d pan.
In the winter I baffle 50% of the regular oil cooler and all of the pan ven
t to reach 170 degrees for the oil. I baffle half of the front air intakes
and put strips of metal tape on the #2 cylinder to limit air flow through
that cylinder and keep the other cylinders at a reasonable temp..
I have 195 hours on the engine and the oil analysis shows normal wear in th
e engine and the oil filter is clean. Next I am going to try overlaying al
uminum screen or perforated metal to limit air flow through the #2 cylinder
. That should reduce the cooling but still keep it uniform on that cylinde
